- Adequacy of study:
- supporting study
- Justification for type of information:
- To register EC453-460-3 under REACH program, a read-across approach for fulfillment of the endpoints has been adopted. EC453-460-3 is an aliphatic ester and fits the description of polyol esters category in HPV program (High Production Volume, US-EPA). The distinguishing feature of polyol esters category is that the fatty acids were linked to one or more of the multiple hydroxyl groups present in the polyol (alcohol portion of ester). The focus of this correspondence is to support read across to EC613-848-7 (target) which provided key studies to determine hazard profile of EC453-460-3 (target), published information on other structurally analogous polyol esters were served as supporting evidence.
